Helpful Links for Understanding Shale

The Shale Project's own page on development:
http://shale.apache.org/building.html

This page is helpful for some initial understanding, however, it has not been updated for quite a while and the information presented on it lags behind the current version of Shale by a few revisions.

IBM's tutorial on understanding JSF and Shale:
http://www-128.ibm.com/developerworks/java/library/j-shale0228/

Once again this information lags behind the current version of Shale by a number of revisions. It is extremely good at giving an explanation of the directory structure of Shale as well as important files for use with Shale.

A Developer's tutorial on Shale:

This is the best site of the three for a full understanding of Shale. Like the others it does lag behind the current version, however, the information contained here is abstracted enough that version is of a lesser concern.
